I think you are just having path issues. Also, you are using a gsp example to test gisp. There are a few shorthands that gsp supports that gisp does not - such as imports starting with /. Gisp will not resolve these.

If you continue to have issues and want to get it working correctly, feel free to email me.

Thank you four your reply. I had my suspicions that might be the issue (the shorthand/differences between gsp/gisp in particular). I also played a bit with the simple factorial example[f] from gisp -- which apparently doesn't work with gps(c) (gisp apparently allows calling casts as functions [eg: (int ImNotAnIntButAfloat)] -- looks like gsp chokes on that.

After some tweaking I couldn't get [f] to work with gsp (but it worked fine with gisp + go build). Looks like both projects could use some more (esp. motivating) examples, and maybe a little more introduction/documentation. At least enough to encourage play :-)

Good call with the casting issue. I'd been seeing that that wasn't working correctly but I just now figured it out.

Gisp lacked the ability to have function arguments actually be functions themselves. Gsp gets around this by casting __all__ (a lazy move, I know) functions to interface{} then to func([arg core.Any]+) core.Any.

I do stop this behavior for a certain whitelist - I need to add int/float64/bool/string to that list I think.

This was definitely just a first step. I think getting the Prelude to work is by far the coolest part. It did actually take a lot of trial and error hacking gisp -> gsp to get it working.

After this I will probably look into self-hosting documentation and maybe a cookbook.

Good to hear :-)

Btw, I'm still not sure what "prelude" means in this context...
